CVE-2025-40130

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The Linux kernel contains a data race condition in the SCSI UFS core related to CPU latency PM QoS request handling. The cpu latency qos add, cpu latency qos remove, and cpu latency qos update request interfaces lack proper synchronization, leading to potential data races and list corruption. This is due to reliance on the pm qos enabled flag, which is insufficient for thread safety. A race condition can occur where one thread deletes a plist node while another thread attempts to use it, resulting in a use-after-free issue. A dedicated mutex has been introduced to serialize PM QoS operations and prevent concurrent access to PM QoS resources.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
